| Abstract Scope |
Cure depth measurements have great potential for rapid process optimization and incoming material qualification in the ceramic vat photopolymerization industry. However, lack of consistency in cure depth measurements between and among labs in academia and industry poses a barrier to technology transfer and standardization. A highly consistent process is required to ensure that small differences in cure depth can be resolved with statistical confidence from the fewest possible number of measurements. This presentation details an approach for optimizing the efficiency of cure depth sample generation and measurement, while maintaining a high degree of measurement repeatability, reliability, and relevance to the printing process. Effects of multiple printing process variables are explored, including slurry dose, projected area, light intensity, and dry time. The impacts of measurement gauge, sample size, operator, and repeated measurements are also investigated. Results showing the impact of machine and material are included, demonstrating applicability to a wide audience. |
